Question

What does the expression "5n" represent?

Answer 1

Answer:

the product of 5 and a number

Step-by-step explanation:

$5n$ is really $5 * n$.

In higher education math, the multiplication sign is not used. A number and a variable (or a equation in grouping symbols) would be just together next to each other. When it's like this, you would have to multiply the numbers.

Example:

$4n; n = 2\\4(2) = 4* 2 = 8$
